我新安装了 Ubuntu 22.04.1，并从标准软件存储库（版本 8.90.0.407）安装了 skype，每 30 秒就会填充/var/log/syslog大量如下所示的 apparmor 消息：

知道如何解决这个问题吗？
答案1
怎么了？
Skype 的安装非常简单。这意味着 Skype 在安全沙箱中运行。您看到的日志来自沙箱，表明 Skype 正在尝试执行不允许的操作。
我该如何解决这个问题？
通过授予 skype 访问权限，可以解决这些特定的错误消息network-observe。
sudo snap connect skype:network-observe
但是，还有一些其他错误消息您作为用户无法解决。这些是由 Skype 访问不需要的内容引起的。Skype 开发人员应该查看这些拒绝并更改应用程序以停止访问这些资源。
真的没有办法关闭这些消息吗？
您可以关闭全部Snap 沙盒拒绝所有应用通过运行以下命令：
echo -n quiet_denied > /sys/module/apparmor/parameters/audit
这将抑制拒绝警告，直到下次启动。
如果您想使其永久生效，则必须使用 grub 指定内核参数。警告：这是一个高级更改，如果您不知道自己在做什么并将其搞乱，这可能会破坏您的系统！
在文件中，在 后面/etc/default/grub添加，如下所示：apparmor.audit=quiet_deniedGRUB_CMDLINE_LINUX_DEFAULT
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor.audit=quiet_denied"
然后运行
sudo update-grub
然后重新启动。
